I have for sale a very closely matched pair of 1943 RCA 5U4G's. Identical date codes of K4E indicates they were made in 1943.

New in original RCA boxes. Full mica construction with 4 "feelers", smooth black plates, bottom foil getters with pill.

No rattles, loose particles, bottoms are tight, perfect as new condition. On a state of the art Amplitrex, one tube tests at 30v forward, 30 v forward, and the other tests at 31v forward, 31 v forward.

If you like RCA 5U4G's, I can't imagine you'd find a nicer pair. Price is $95.00 plus $10.00 for Priority Mail shipping in a oversized box. Paypal preferred, US sales only. Full refund if sent back within with ten days (if you're not satisifed), you pay return shipping.
